A Methodology for Unified Assessment of Physical and Geographical Dependencies of Wide Area Measurement Systems in Smart Grids
Wide Area Measurement Systems (WAMS) enable real time monitoring and control of smart grids by combining digital measurement devices, communication and control systems. As WAMS consist of various infrastructures, they imply complex dependencies among their underlying systems and components of different types, such as cyber, physical and geographical dependencies. Although several works exist in...
متن کاملNeuro-Fuzzy Based Algorithm for Online Dynamic Voltage Stability Status Prediction Using Wide-Area Phasor Measurements
In this paper, a novel neuro-fuzzy based method combined with a feature selection technique is proposed for online dynamic voltage stability status prediction of power system. This technique uses synchronized phasors measured by phasor measurement units (PMUs) in a wide-area measurement system. In order to minimize the number of neuro-fuzzy inputs, training time and complication of neuro-fuzzy ...
متن کاملImproving Monitoring, Control and Protection of Power Grid Using Wide Area Synchro-Phasor Measurements
When disturbances occur in power grid, monitoring, control and protection systems are required to stop the grid degradation, restore it to a normal state, and hence minimize their effects. However, in wide area power grid resulting from large extension and interconnection with neighbor grids, classical systems based on local independent measurements and decisions are not able to consider the ov...
متن کاملDesign of H Robust Damping Controllers of FACTS Devices with Considering Time - delay of Wide - area Signals
1 Abstract-This paper proposed the design of wide-area robust damping (WARD) controller for multiple Flexible AC Transmission Systems (FACTS) devices to enhance the stability of power system with considering time delay of wide-area signals. Firstly, as power systems interconnect more and more to exchange large amounts, wide-area measurement system (WAMS) is widely applied to monitor and control...
متن کاملSmartWAMS-The approaches for stability improvement in power system
The main cause of wide-area disruptions in the present power network is due to the relatively long transmission lines between regions, the continuous load growth without a corresponding increase in transmission network capacities. This disturbances have stressed power systems further and forced them operate closer to voltage and angle instabilities. As a result, stability of such power systems ...
متن کاملThe Role of Organizational Structure in Designing Performance Measurement Systems
Organizational structure determines the scope of decisions, tasks, responsibilities, goals, perspectives and rewards for achieving results. In recent decades, due to environmental changes and dramatic technological advances, organizational structure has changed from Mechanistic to organic. The purpose of the restructuring is to facilitate the achievement of the organization's goals. Changing st...
